I've found a jig to be most effective in walking pace/slightly faster then walking pace current.
When using a jig, there's no need to be hugging the bottom at all. personally if I was fishing 6' of water, I'd have a 3-3.5 foot leader. Fish will come up to jig, and this keeps it away from bottom debris. the absolute key to fishing jig is to be DEAD DRIFTED. Any resistance on the line, and your jig will swing up, and be for the most part be rendered useless.
I don't get how someone can say fishing a jig is a waste of money or time. I often use the same jig all day...how is that expensive? Not to mention there's no bait or mess involved, besides occasional adding of scent.
It takes confidence to successfully fish any style, I can see how if you've never caught fish on jigs before,it would be easy to second guess yourself when starting to fish for steelies. My advice would be to bust out some jigs when chums are around, figure out what works with those fish, then use those techniques for steelies. good luck out there. and remember absolute dead drift.
